Don Cooper to sign multi-year deal with the Sox [UPDATE]

A contract extension for White Sox pitching coach Don Cooper figures to become official on Tuesday afternoon with the announcement of a new multi-year deal that will precede a two-game stint as manager in place of Ozzie Guillen.

Cooper is finishing his ninth full season and 10th overall as Chicago’s pitching coach, having begun the task on July 22, 2002. He has worked under managers Jerry Manuel and Guillen, and soon will be practicing his craft for a third — whomever is hired during the offseason to replace Guillen.

With Guillen released from his contract after Monday’s 4-3 victory over the Blue Jays to pursue other opportunities and bench coach Joey Cora apparently heading to the Marlins with Guillen, Cooper will run the show over the final two days of the 2011 season as the team’s interim manager.

CSN reports first base coach Harold Baines will get a multi-year deal too, but third base coach Jeff Cox and hitting coach Greg Walker won’t get new deals.

UPDATE: The extension is for 4 years:

Of Cooper, Williams said, “Well, the pitching has been as consistent over the last decade, and that’s a testament to our scouting department, to our player development department, to Don Cooper, directly in his direction. It’s something that’s well deserved and I’m happy, thrilled to know that he’s going to be on board here for the next four years.”
